MATRIX-DISTRIBUTING- MECHANISM.

To all whom it may concem:

Be it known that I, HANS PETERSEN, a I

citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Matrix-Distributing Mechanism, of which the following is a specification.

This invention relates to improvements in matrix distributing mechanism for linotype machines.

In machines of this nature. after the casting operation, difficulty is experienced in returning the thicker matrices to the magazine, the larger or thicker matrices owing to their size and their movement along the distributer bar at right angles to the chambers of the magazine, indropping from the distributer bar strike the partition walls of the magazine, making it necessary to provide an excess of space between the partition walls of the magazine. It is the object of the present invention to overcome this difficulty, and to this end the invention comprehends a matrix provided with a beveled face extending completely across its lower end and located at the forward side of the matrix facing in the direction of travel thereof along the distributer bar. said beveled face being adapted to engage the partition walls of the magazine and acting to guide the matrix into the channel entrance. It will be understood that this construction is designed chiefly for the thicker matrices and that the invention comprehends employing thick matrices of this form with thin matrices as commonly constructed having rectangular shaped lower ends, and an important feature of the invention also resides in the provision of a special construction of distributer lift capable of lifting either a thick beveled matrix or a thin unbeveled matrix and functioning in the usual way to lift only a single matrix at each lifting movement.

The invention, with other objects and advantages thereof, and the particular construction, combination, and arrangement of parts comprising the same will be under stood from the hereinafter contained detail description when considered in connection with the accompanying drawings-forming part hereof and illustrating one embodiment of the invention.

Specification of Letters Yatent.

Application filed August 27, 1918. Serial No. 251,684.

Patented Sept. 23, 1919.

Figure 1 is a slde elevation of distributer mechanism including a distributer lift constructed in accordance with the present invention.

Fig. 2 is a side elevation, on an enlarged scale, of the distributer lift engaging one of the thick beveled matrices.

Fig. 3 is a similar view showing the distributer lift engaging one of the thin unbeveled matrices.

Figs. 4 and 5 are detail views of one of the thick beveled matrices.

Referring to a detail description of the drawings wherein like reference characters deslgnates corresponding parts throughout the several views, 1 deslgnates the distributer box, 2 the conveyer screws, 8 the distributer bar and 4 the magazine having partition walls 4, all of usual construction, the matrices after thecastin operation being fed from the distributer ox 1 to the conveyer screws and moved thereby along the distributer bar from the magazine to their respective channels or compartments of the magazine.

Referring particularly to Figs. 4 and 5 of the drawings, A designates one of the thick matrices having the usual supporting ears a, the matrix character a on one edge face thereof, and the distributer teeth a at its upper end. In accordance with the present invention the matrix A is provided with a beveled face 6 extending completely across its lower end. The beveled face 6 is located at the forward or front side of the matrix facing in the direction of travel of the matrix along the distributer bar 3 indicated by the arrow. These beveled faces 6 of the thick matrices, are adapted, upon the dropping of the matrices from the distributer bar, to engage the partition walls 4 of the magazine so that, if, as the tendency is, the matrices do not drop from the bar at the intended lace along the same but are carried slight y beyond this point, they will not catch or hang upon the partition walls 4' of the magazine but the beveled faces of the matrices, disposed at the front side thereof facing the direction of travel will engage the partition walls and serve to guide the matrices into the entrance of the particular channel or com artment,th1s construction permitting of t "e use of matrices An important feature of the invention also resides in the provision, in combination with the improved matrix structure, of a special construction of distributer lift capable of operating with both styles of matrices, the

thick beveled ones and the matrices of minimum width having rectangular shaped lower ends, the distributer lift operating in the usual manner to lifta single matrix at each: lifting operation. Referring particui5 'larly to Figs. 1, 2 and 3 ofzthedrawings, 6

designates a distributer lift constructed in tributer lift having a matrix engaging part accordance with the invention. Theflift 6 is in. the form of a blade or finger having a matrix engaging. part at its upper end comprising a'stra'ight shoulder portion 7 "and abeveled lip 8' at one side thereof. The straight shoulder portion 7 is of a width equal to the minimum width of the thinnest matrices intended to be employed, and the beveled lip 8 is formed to correspond to the bevel faces I) of the thick matrices; As will be understood this construction of lift is capable of effectually performing its function witheither the thin unbeveled matrix or the thick beveled matrices In operating 3Ere1e'd matrices, thebeveled lip 8 engages the beveled faces b'of the matrices and" the straight shoulder portion 8 engages the lower ends'of thematrices beyond'the beveledfaoes b.

40- -Any suitable operating means may be employed for the dist'ributer lift, to recip- *rocate the same at each revolution of the distributer screws. In the drawings I have shown the distributer lift 6 connected with one of the well known forms of lift operating 1nea ns, said means comprising a vertlcally swinging rock arm 9 connected with i a leverlO actuated by a cam 11 mounted on the rear upper conveyer screw andengag ing a roller 12 journaled on the lever 9, the distributer lift being securedat its lower end to the outer end of the vertically swing ingarm 9. a l

While I have illustrated in the drawings a specific embodiment of the invention, it.

will be understood that minor changes and variations in the particular construction shown as will appeal to those skilled in the art and falling within the scope of the appended claims may be'practisedwithout departing from'the spirit of the invention.

What I claim is 1. Inca. linotype machine the combination of distributer mechanism, including a dis-' comprising a straight shoulder portion and an inclined lip at one side thereof. and matrice having: beveled faces extending completely across their lower ends at the-'- forward side thereof facing in the direction of travel of the matrices. I

2. In a linotype machine, the combination of distributer mechanism including a distributer lift havinga matrix engaging, part,

an inclined lip atone side thereof, matrices having rectangular shaped lower endsand V beveled faces vextending completely-across their lower ends at the forward side thereof;

facing in the direction of travel thereof.

3.' In a linotype machine the combination of distributer mechanism including pajdistributer lift havinga straight shoulder with thin matrices", having rectangular shaped across-the lower endsthereof, said distriba beveled lip at one side thereof, relatively uter lift being capable of lifting one atia, Y

7 time the: matrices of minimum width having In testimony whereof I aflix my signature.
